I have a webserver with ssh access and the possibility to enter a cron job there.

I have another second webserver, where I just can create web pages to do some work (via php) when they are called from outside.

What’s the best way to automate those tasks by using a cron job on the first one?
I found python3 and webbrowser in general available on that first (cron job) web server.

When testing interactively, a text based browser pops up and requires a q(uit) command to be entered.
Before going that path any further (How to enter input to a shell script running in background ?) I’d rather ask if there’s a better way to solve my problem.
